Title: Bag body having diagonal seal part, and sealing device of the bag body
Inventor: NAGASAKA SHIGEAKI
IPC: B65D30/10
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To appropriately regulate the size of an outlet according to the characteristic of the content in a bag body to form the outlet through the diagonal cutting from a seal part to an adjacent side edge by setting the seal angle relative to the adjacent side edge of the seal part according to the content. SOLUTION: Side edges 12, 13 and a bottom side 14 of a bag body 1 are sealed, the fluid content is filled in the bag body in a condition where a diagonal seal part 11 is opened, and the diagonal seal part 11 is thermally fused. The diagonal seal part 11 is fused on one adjacent side edge 12 at the seal angle θ1 which is appropriately set according to the characteristic of the content, e.g. the viscosity. When the content is taken out of the bag body 1, the θ1 side forming an acute angle is diagonally cut when the viscosity of the content is small. The outlet is thus lower and the content is difficult to overflow. On the other hand, when the viscosity of the content is high and the content is difficult to flow, the θ2 side forming an obtuse angle is diagonally cut. The content can thus be taken out in a short time.

IPC: G03G15/08
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a multi-color image forming device equipped with the density detection means of a patch and the exchange means of two-component developer and constituted so that an image without the lowering of density and fogging can be formed even when the device is used for a long term by automatically exchanging the developer when density is judged to be lowered caused by the deterioration of the developer and the non-working time of the device can be reduced. SOLUTION: After a photoreceptor belt 1 is primarily electrified and the whole surface thereof is exposed, it is secondarily electrified and the latent image of the patch with the maximum density is formed by a second exposure action. After the prescribed potential of the latent image is confirmed by a potential sensor, the latent image is developed by a second developing unit (two-component developing unit) 7a and the density of the obtained patch is measured by a transmission density sensor 60. Then, a density signal is transmitted to a CPU and compared with a previously set reference signal. When it is smaller than the reference signal, it is judged that the density is lowered. After it is confirmed that mixing ratio is not abnormal, it is judged that the developer is deteriorated. Then, the developer of the second developing unit 7a is exchanged by the automatic exchange means.

Title: Recording device
Inventor: HANIYU YOSHIAKI
IPC: B41J5/30
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To transfer data efficiently inside a recording device so as to shorten a printing time, by composing a printer controller so that in the case band information is all white data, the band information is not transferred to an engine controller but notice that the band information is all white data is transferred. SOLUTION: A printer controller 4 judges whether band information to be transferred to an engine controller 5 is white data or not. In the case there is band information to be transferred, the controller transfers it. In the case the information is all white data, it notifies the engine controller 5 of it, and proceeds, without transferring band data, to wait for receiving the next band data. On the other hand, in the case there is data received from the printer controller 4, the engine controller 5 judges whether the notice is about band information including image data or all white data. Therefore, an amount of data transferred from the printer controller to the engine controller and a transfer time are reduced.
